richutd18:As an alternative to purchasing an amp, can a zp120 be used in the same manner as an amp? Also the ZP120 having a dedicated sub out, Can this be used when Av amp is not in use without having to unplug phonos?
Do you mean a Sonos ZP120? They don't have a dedicated sub-out, at least I've never noticed one on mine (they don't have any line-outs at all in fact). Could you use it instead of a stereo amp, I guess so, it's a got a line-in but I'm not sure how you'd get on getting the volume levels right, might need a bit of adjusting each time. I really don't think the amp in a ZP120 has got the grunt to run alongside the Denon either to be honest.
